To provide a reciprocating compressor capable of preventing deformation of a bush provided between an eccentric shaft and an eccentric shaft support hole of a connecting rod.

This reciprocating compressor has a piston receiving power from the eccentric shaft to compress refrigerant by reciprocating, the eccentric shaft support hole 25a connected with the eccentric shaft at one end, the connecting rod 25 converting rotary movement of the eccentric shaft to linear reciprocating movement to transmit it to the piston, the bush 26 arranged between the eccentric shaft support hole 25a and the eccentric shaft to fill a sapce between the eccentric shaft support hole 25a and the eccentric shaft and having a hinge hole 26a in which the eccentric shaft is rotatably inserted, a pushing-in channel 25c provided in either of the eccentric shaft support hole 25a and the bush 26, and a pushing-in projection 26b provided in the other of the eccentric shaft support hole 25c and the bush 26, protruding in such a shape corresponding to the pushing-in channel 25c, and pushed into the pushing-in channel 25c.
